UPDATE 1-France must extend nuclear reactor lifespans-audit

* Some 22 nuclear reactors will reach 40 years old by 2022

* EDF wants to extend reactors lifespan to 60 years

* Heavy investments needed in short, medium term (Updates with quotes, reactions)

PARIS, Jan 31 (Reuters) - France has no option but to extend the lifespan of existing nuclear plants, because any investments in new nuclear capacity or an increase in its reliance on other forms of energy would be too costly and come too late, the French Court of Audit said.

The French independent government body, which is charged with conducting financial and legislative audits, said in a report that a lack of investment decisions to build new reactors meant there were few choices left.

"In the absence of investment decisions, an implicit decision has already been made that commits France either to prolong the reactors' lifespan beyond 40 years or to quickly change the energy mix, which implies more investment," said the report on the costs of the French nuclear power sector.

By the end of 2022, 22 out the 58 reactors in France, the world's most nuclear-reliant country, will have been in operation for 40 years.

The report, published on Tuesday, said that if the reactors' lifespan was limited to 40 years, this would mean having to build 11 new-generation reactors by 2022.

"Putting in place such an investment programme in the short term is highly unlikely, even impossible," it said.


Greenpeace said the failure to make any investment decisions in the past is resulting at higher financial costs and putting the population at risk.

The failure to invest is "in total contempt of the nuclear safety authority (ASN), which is the only authority entitled to decide whether to extend the lifespan of reactors," said Sophia Majnoni, who is in charge of nuclear at Greenpeace France.

State-owned utility EDF, which operates all of France's reactors, has said it aims to extend their lifespan to 60 years, but there is no official limit to their functioning. The bulk of French reactors were built in the 1980s and 1990s.

The Court of Audit also said that to maintain the current level of electricity production, heavy investments would be needed in the short and medium term, including a doubling of maintenance investments, which would in turn push production costs up by 10 percent.

The Court recommended that the choice of the future of the energy mix should not be made in an implicit manner but that a strategy should be explicitly elaborated, debated and adopted.

French energy minister Eric Besson said in a Twitter post that even if the costs of nuclear power rose by 10 percent, it would remain the cheapest form of energy after hydro-power.

Uncertainty on Future Costs

The Court of Audit said French nuclear companies, including Areva and EDF, had taken into account all costs related to nuclear energy but that there was still a great deal of uncertainty regarding future costs.

"This uncertainty cannot be lifted for the moment, because we have not gone through the concrete experience of dismantling reactors or putting in place the deep burial of radioactive waste," Didier Migaud, the head of the Court of Audit, told a news briefing.

France's nuclear energy waste management agency (ANDRA) pegged future costs for storage at 35 billion euros in 2010, up from 15 billion euros in 2005, with a new cost level to be announced at the end of 2012.

EDF's investments costs to upgrade the reactions could reach 3.7 billion euros per year, including work imposed by ASN earlier this month to prevent a nuclear disaster such as Japan's Fukushima accident, the report added.

The report's conclusions echo a leaked draft government study on Monday, which said that extending the life of France's reactors would be a cheaper investment option to 2035-2040 than building any type of new power plant.

The leaked government study on energy scenarios for France until 2050, due to be published in its final form on Feb. 13, shows that such extensions would cost 680 million to 860 million euros per reactor.

Presidential Campaign

That would compare to the roughly 5-6 billion euros ($6.56-$7.87 billion) it would cost to build a new-generation reactor such as the 1,600 megawatt EPR reactor constructed by state-controlled Areva.

The Court of Audit report, commissioned by Prime Minister Francois Fillon in May 2011, comes as France's reliance on nuclear power has become part of the country's presidential campaign in the aftermath of Japan's nuclear disaster in March.

While the ruling UMP party plans to maintain the country's nuclear share of 75 percent in the electricity mix, the highest in the world, socialist candidate Francois Hollande said he would bring down that share to 50 percent by 2025.

Hollande, campaigning against President Nicolas Sarkozy, has said that if elected he would close France's oldest plant, Fessenheim, toning down earlier plans as part of a pact with the Green party to shut 24 reactors by 2025.

The Fessenheim plant, one of 19 across the country, houses two 900-megawatt reactors.

France first opted for a full-blown nuclear energy programme with minimal public debate after the first oil crisis in 1974 and continued to support nuclear power after the 1986 Chernobyl disaster.
